When using EEVEE on high resolution monitors the light buffers might not
get initialized as there are range checks that pass in the first try.
- number of tiles needed is larger than the max_tile_count_threshold
- total_word_count is smaller than max_word_count_threshold as it is
never set (still initialized to zero.
Solution is to not exit on the first try. In a later stage we might want
to use something that doesn't require any looping.

Now that the select engine data uses non-trivial objects in its global
data, storing it at the global scope causes trouble due to arbitrary
construction and destruction order. Instead use the construct on first use
idiom to make the order clear. Though this struct probably shouldn't be
static at all, it does simplify memory management as well, it's nice to
remove the need to manually clear the arrays.

- Remove unlimited mip level.
- Make computation of sampling region simpler.
- Add correct mirroring of UV and border region.
- Fix crash when world probe is smaller than lightprobes.
The storage coordinate is left unchanged and is
kept as `ReflectionProbeAtlasCoordinate`.
A new structure `ReflectionProbeCoordinate`
contain scale and offset for efficient sampling
without integer math.
The `ReflectionProbeWriteCoordinate` is only used
during the octahedral map processing.
This also has the benefit to centralize the coordinate
changes to a single class.

The previous commit introduced a new `RPT_()` macro to translate
strings which are not tooltips or regular interface elements, but
longer reports or statuses.
This commit uses the new macro to translate many strings all over the
UI.
Most of it is a simple replace from `TIP_()` or `IFACE_()` to
`RPT_()`, but there are some additional changes:
- A few translations inside `BKE_report()` are removed altogether
because they are already handled by the translation system.
- Messages inside `UI_but_disable()` are no longer translated
manually, but they are handled by a new regex in the translation
system.

This adds support for rendering the hardness curve attribute.
The attribute cannot be written from within GPv3, but is added when
converting from the legacy Grease Pencil type.
This doesn't seem to offer a lot of benefit but it is the
way it should be.
Other area could make use of this later and the
implementation could be supported at the gpu module level.
Even if related, they don't have the same performance
impact.
To avoid any performance hit, we replace the Diffuse
by a Subsurface Closure for legacy EEVEE and
use the subsurface closure only where needed for
EEVEE-Next leveraging the random sampling.
This increases the compatibility with cycles that
doesn't modulate the radius of the subsurface anymore.
This change is only present in EEVEE-Next.
This commit changes the principled BSDF code so that
it is easier to follow the flow of data.
For legacy EEVEE, the SSS switch is moved to a
`radius == -1` check.
This avoid the cost of creating the tiles themselves which uses a lot
texture write. This was a bottleneck on Apple GPUs.
Also the per pixel classification allows us to remove certain checks in
the deferred lighting shader making it faster.
### TODO
- [x] Add gl_FragStencilRefARB support on other backend
- [x] Add workaround for when gl_FragStencilRefARB isnt supported

This modify most shader using the GBuffer to use the
`ClosureUndetermined`. This in turn reduces the amount
of duplicated data in the `GBufferReader` structure.
The most important part is the usage of fixed array
indices to access the `GBufferReader.closures[]`.
This avoid the struct to be moved from local register
to device memory and remove a huge performance penalty.

This refactors the whole pipeline to be closure agnostic.
This mean we can have only one raytracing step that covers
any closure type. In practice, it means that there is
3 objects having 1 closure each with a different closure
types each, we can run the raytracing once.
This create a huge overhead during the tile classification
stage. This is fixed by #116772 and will be merged separately.
